This was an extremely large, completely silent rectangular object with its corners cut round like a playing card. White in colour with very bright white patches which seemed to move across it's surface as if torch beams were being aimed onto it. Extremely frightening experience as i walked the perimeter of a field close to my house with the dog the object caught my eye, as i live right beside Glasgow airport here in Scotland my first thought was that this was just an aeroplane until i looked again, taking it in for about 1 minute until it flashed along the sky in a way that is hard to explain, it was there, then it was about 20 feet to the west, then another twenty and then it was gone. It wasn't a constant motion, it was like blinking. Im usually a rational person and have never believed in anything like alien life, nor am i religious in any way, but after thinking about this for a couple of hours i can't put any explanation to it. It was so close to me and so large. Tonight i'm not going to sleep, too scared. My wife says she wants to believe me but she says she'd have to see it for herself, but i know what i saw and this thing wasnt anything man made, the material it was made of looked like skin, its still vivid in my minds eye.
